To all whom it may concern Be it known that 'I," VAGLAV OTAKAR DEYL, a. subject of the, Emperor of Austria- Hungary, residing at Vinor, near Prague,

Bohemia, Austria-Hungary, have invented,

certain new and useful Improvements in ltoot-l larvesters, ofavhich the following is a specification. p p

This invention relates :to atdevice for ejecting roots in harvesting machines.

The invention comprises one. or two rotatable spindles arranged behind the lifting knives andyarranged so as to rise toward the back in the longitudinal direction of the machine. 'ihese spindles are set with suitable projecting parts, so that the lump of earth forced upward owing to the inclination of the knives, comes together with-the roots under the action of the project ng parts which gradually remove the earth from the roots or reduce the lump of earth to small particles and then project the roots together with the remains of the earth, to the side from the center of the machine. The harvesting by means of this device re quires a very small consumption of power and has the further advantage that the roots are neither. damaged nor covered with earth. The projecting parts not so that during that part of the revolution which is above the spindle, they reduce the lump of earth to small particles as already stated, and during that part of the revolution that is below the spindle, close the furrow produced.

A construction according to this invention for root crops is shown by way of example in the accompanying drawing in plan.

."Xccording to. the drawing, on the wheel axle 1 is rotatably mounted the knife frame 2 which, by means of two rods 3 connected to levers 4, the other ends of the levers being mounted on a spindle 5 which rotates in hearings on the machine frame and provided with a hand lever 6, can be lowered into the operative position, or raised up out of it. To the knife frame aresecured in the known manner the knives a, b, or a trough-like knife. Behind one of the two knives, for instance behind the knife a, is arranged a spindle 7 which extends in a vertical plane parallel to the center line of the machine, slightly rising toward the rear.

his spindle is set with suitable projecting parts, for instance, with hoop-like'members gradually, increases from the front back- Specification of Letters'Patent. Pgfiggntgd A ggfl, T915, pplication filediNovember 13, 1913. Seria1N o. 800,77 3,

8 or shovels or prongs, the length of which ward and the said parts being distributed on the spindle in a helical line. he front end of the spindle is supported either in a bearing 9 secured to the knife a itself, or in an arm' secured to the knife frame. The rear end ofthe spindle is supported by the lug 10 and is rotated in any suitable manner, for. instance by the driving wheel or by a motor in the direction of thearrow ll, that is to say, in an anti-clockwise direction looking from theback of the machine. To theother knife 7) or to an arm secured to the knife frame, are secured bars 11.

It will be seen that the lum-pof earth eX- "cavatcd together with the roots. owing to upward obliquely until it comes within reach of the projecting parts 8, the shorter of which gradually throw off the earth from the root at II, whereupon the longer project ing arms throw the roots together with the remains of the earth, from the center of the machine in the direction of the arrows L l, approximately up to the wall 12. In that way, the projecting parts act during the upper half of the revolution of the spindle, while during the lower half of the revolu tion they close the furrow with earth. ihe bars 11 act in such away that they guide the lump of earth lifted out, toward the proj eating parts, during which time they allow part of the earth to drop through but prevent the roots from passing, so that the roots in this construction are ejected only at one side (atlll). Instead of the bars, a sheet of metal can also be used.

f the roots are to be ejected at both sides, a second spindle 7 with projecting parts 8 identical with that described is provided, instead of the bars 11, but rotated in the opposite direction.

What I claim as my invention and desire to secure by Letters Patent is:

1. A root harvester comprising a frame, digging means carried by said frame, a spindle arranged behind said digging means, projecting U-shape parts on said spindle, and means for rotating said spindle so that said projecting parts move away from the center line of the machine during the upper part of their rotation.

- spindle arranged behind said digging means,

bearings at each end of said spindle, said "back bearing being higher than said front Copies of this patent may be obtained for bearing, projecting U-shape parts on said spindle lncreasing in size toward the back of the machine, and means for rotating said spindle so'that said projecting parts move away from the center line of the machine during the upper part oftheir rotation.

4. A root harvester comprising a frame, lifting knivescarried by said frame, a hear ing on one of saidlifting knives, a bearing on the back of the frame arranged higher than the bearing on the knife, a spindle in said bearings, projecting parts on said spindle, means for rotating said spindle so that the projecting parts move away from the center line of the machine during the upper part of their rotation, and means arranged on the other lifting knife so that the piece of earth lifted by the knives is guided toward the spindle.

5. A root harvester ing on one of said lifting knives, a bearing on the back of the frame arranged higher comprising a frame, l1ft1ng knlves carried by said frame, a bearthan the bearing on the knife, a spindle in said bearings, projecting parts on said spindle, means for rotating said spindle so that the projecting parts move away 7 from the center line of the machine during the upper part of their rotation, and bars arranged on the'other lifting knife so that the piece of earth lifted by the knives is guided toward the spindle.
